# Original version of this script had no license; modified version

# 20240905 bkw: BUILD=2
# - new maintainer.
# - actually test against some .dbf files, found here:
#   https://github.com/infused/dbf/tree/master/spec/fixtures
#   not all of them are in supported versions of the .dbf format,
#   but at least some of them work fine.
# - add a patch from Debian.
# - add a patch to fix grammar/spelling/usage in the man page.
# - get rid of unneeded makefile.diff.

# Note: this is more for digital archaeology than anything else.
